the only time someone will ever have to stuff the joint is if that person rolling is a bad roller. and rolls the joint to loose. therefore pushung down the weed in the joint with something like the aglet on a sweater string, or a pencil or headphone connecting thingy. sometimes good rollers need to styff tge joint abit, but only in rare cases

friend1: hey wanna roll the j this time

friend2: idk man im not to skilled at rollimg
friend1: comeon guve it a try

friend2: okaay i guess

friend1:you made the joint to loose now you gotta stuff the joint. idk if theres enough kush for that man
